Problems solved by technology

In the past, the electrolysis workshop used the method of burning and baking waste effect rods in principle. However, due to the current subjective thinking of reducing costs and increasing efficiency, the use of effect rods is relatively sufficient, and other wastes such as waste leather tubes and dead wood trunks will also be considered. Material replacement, because part of the combustibles are less flammable, gasoline is usually used to support the combustion, not only the smoke is lingering during the baking process, but also the ash of rubber and plastic is released, which also causes secondary pollution to the originally poor environme

Example Embodiment

[0021] The following describes the implementation of the present invention in detail with reference to examples.

[0022] A method for baking and electrolysis of aluminum ladle, including the following steps:

[0023] 1. Use a crane to hoist it on the bag holder. First, pour the cooled carbon residue into the bag to be pavement. The carbon residue can be laid on the bottom of the bag about 2cm thick, and the carbon residue will serve as a buffer for heat transfer. It can prevent the hot anode from directly contacting the bottom of the package and causing the lining to overheat and crack.

[0024] 2. Place the newly swapped poles for about forty to fifty minutes after cleaning and cleaning the poles to allow the poles to cool down. When the surface temperature is about 200°C, use a crane to hoist the poles into the carrying bag. Place the carrying bag cover plate made of insulating mica board in advance on the carrying bag for about 90±30 minutes.

[0025] 3. Put another newly replace...

Abstract

The invention discloses a method for electrolyzing out an aluminum two-man ladle through baking. The method comprises the steps that a two-man ladle is lifted to a two-man ladle frame through a crown block at first, and cooled carbon residues are poured into the two-man ladle for bedding; a newly swap-out anode scrap is lifted into the two-man ladle through the crown block after being placed and cooled to be 200 DEG C and is covered with a two-man ladle cover plate, and the situation is kept for 90+/-30mins; the two-man ladle cover plate is opened at last, the other newly swap-out anode scrap is lifted into the two-man ladle through the crown block after being placed and cooled to be 400+/-50 DEG C and is covered with the two-man ladle cover plate, and baking at 500 DEG C is conducted for 24+/-1 hours. According to the method for electrolyzing out the aluminum two-man ladle through baking, the existing high temperature conditions of an electrolytic plant are utilized, an electrolytic bath is used for swapping out preheating of the anode scraps to bake the ladle, high efficiency and low consumption are achieved, work load of workers for gathering fuel is greatly reduced, and the environment-friendly and safe operation is really achieved.

Description

technical field [0001] The invention relates to a method for baking and electrolyzing aluminum ladles. Background technique [0002] At present, some 180KA pre-baked aluminum electrolytic cells have a load limit of 5 tons for the ladle, and the service life is 15 years. During the production process, due to various reasons, the lining of the ladle will be damaged to varying degrees, so every time the ladle is used The lining needs to be refurbished once a year. In the furnace repair factory, the inner lining of the ladle is rebuilt with heat-insulating materials such as refractory bricks and red mud, and then returned to the electrolysis workshop. Since the newly built inner lining of the ladle has not The water evaporation treatment is carried out, and the overall environment is relatively humid. At this time, when it comes into contact with high-temperature molten aluminum, dangerous situations such as explosion, splashing of molten aluminum, and impact of hot air will occ...
